PRINTERS CHASE.

Specification forming part of Letters Patent No. 52,662, dated February20, 1866.

To all whom it may concern:

Be it known that I, ALLEN M. BLANCHARD, of the city and county of St.Louis and State ot' Missouri, have invented a new Adjustable PrintersChase; and I do hereby declare that the following is a full, clear, andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

Figure l ot' the annexed drawings represents a plan ot the improvedchase when all its parts are put together in working order. Fig. 2 is anelevation of one of the side pieces alone.

The object of this invention is to produce a chase that printers canreadily adjust to any required size of job matter that may be requiredin any country oflice or other place where a large number ot' chasesot'dit'terent sizes would be both troublesome and expensive.

In addition to the improvement of the chase so as to require a lessernumber of them, another advantage arises in the mode of securing thematter in them, which is done without the usual number ot quoins, whichthe old method requires, the several bars of the chase being locked upon the outside.

To enable those skilled in the art to make and use my chase, I willproceed to describe its construction and operation.

I take four straight metallic bars, A, one end of which, A', is madethicker than the rest of the bar, so as to allow the recess b to be madein the thick end part ot' a depth equal to the thickness of the rest ofthe bar. The width of the recess b should be more than the width of thebar, so that when the latter is laid in one ot' the recesses it can bemoved easily backward or forward, and will readily admit of the key Bbeing driven in alongside ot' it, as shown in the drawings. A grooveshould becut in the outer edge of each of the pieces A for the receptionof the wedge or key B, so that when the key is driven in the bar cannotrise up out ot the recess.

In lieu of using the key B, a hole may be made in the outer end of thethickened part ot' the bar parallel with the axis ot' 'the bar, and aset-screw, C, fitted therein.

After the chase has been adjusted to the form the set-screws may bescrewed up tight, and in this case the keys B will be dispensed with, asthe screws will be all that'will be needed to fasten the chase onto theform.

Having described my invention, what I claim is- I A printers chaseformed of four straight bars, A, fitted together so they may be adjustedto any size of form required without the use of quoins, substantially asset forth.
